Product Page Dedicated FAQ
Q1: What is ZnS used for in optics?
A: ZnS is a widely used infrared optical material, mainly manufactured into windows and lenses for thermal imaging, infrared detection, defense optoelectronic systems and industrial temperature measurement devices. It performs stably in the common mid and far infrared bands.
Q2: What is the difference between ZnS and ZnSe?
A: Both are mainstream IR materials. ZnS has lower cost, better mechanical strength and good machinability, fit for conventional infrared equipment. ZnSe has wider transmission range and higher transmittance, more suitable for high-precision infrared lasers and high-end optical systems.
Q3: Can you apply anti-reflection coating on ZnS components?
A: Yes. We offer professional infrared anti-reflection coating on single side or double side, which can effectively improve infrared light transmittance and reduce reflection loss.
Q4: What is your minimum order quantity for custom ZnS optics?
A: We support small batch orders. Standard parts are in stock, and customized products can start from a single piece.
Q5: Is ZnS suitable for outdoor long-term use?
A: ZnS has stable physical properties under normal temperature and dry outdoor environment. For high humidity or severe corrosive conditions, we suggest adding protective coating to extend service life.
